Excellent! Thanks for the tip, Denzil - I'm sure that Mrs.Nopax would love to visit Cannes, and once we are there, well....
Reminds of of a place in Poitiers, called 'Chez Manuel' It's a museum rather than a shop, but filled with a centuries' worth of French domestic and agricultural ephemera. It has a Sikorsky HSS-1 (S-58/H-34) in the back garden, sadly now looking quite poorly after years in the outside. Also one of those little Nords on the roof.
Well worth a visit - it's on the main road North out of the town.
Returning to the main subject, the B-57 in question is an EB-57E, it was a Davis-Monthan (AMARC/MASDC) some years back - I don't yet know how it ended up in France.
